SPECIFICATION forming part of Letters Patent No. 301,981, dated July 15,1884.

I Application filed Auguste-1883. model.)

.for merchants or manufacturers price and sample cards, or packages ofwritten, printed,

or othermatter.

The invention consists in the combination, with the covers of theholder, of a binder formed of two relatively-fixed plates, between whicha strip is clamped securely, and by which strip the binder is fastenedto the covers, and a pivoted movable clamping-plate,

- which acts over and with the inner fasteningstrip-holding plate, tobind the book or articles to be held firmly but removably to the covers.

The invention includes, also, special con-- in which similar letters ofreference indicate corresponding parts in all the figures.

Figure 1 is a front perspective View of the binder detached from itscovers. Fig. 2 is'a crosssectional elevation of the binder, alongitudinal section of the covers to which it is applied, and an edgeview or section of a memorandum-book held by the binder within thecovers; and Fig. 3 is a rear perspective view of one end of the binderwith its fastening-strip removed.

tically an integral part of the cover, consists of four principalparts-viz., a bed or base plate, 6, an intermediate lower clamp-plate,f,

an upper movable clamp-plate, g, and a flexible strip, h, confinedbetween platese f, and projecting at each side in suitable flaps i, bywhich the binder is attached to the covers a. The plates 6 f g arepreferably stamped from sheet metal, such as brass but any suitablematerial may be employed. The plate 6 is bentat about a right angle toform a back piece, 0, and a bed-piece, c and I form 011 or fix to theplate 0 at each end and next its outside edge the ear or lip said lipsrising from the body of piece 6 at about right angles thereto, as shown.The plate 9 has a clamping-jaw, g, bent at about a right angle with itsbody portion, the edge of which jaw may be .either plain or serrated, asdesired, and the jaw ghas pivot-pins g one at each end by which theplate 9 is pivoted in the lips j of plate 6. The pins 9 are arrangedinside of or eccentrically to the gripping-edge of j aw g, to

grasp the book or papers to be held with a gradually-increasing force asthe jaw is pressed downwardtoward the vertical position. The plate j isbent twice longitudinally and at about right angles into a bed-piece, f,a back piece, f and an overhanging flange-piece, f thereby forming apocket, 70, to receive the back of a memorandum-book or other package,Z, to be bound. A gripping projection or bead, m, is formed along theouter edge of plate f, and rises from the inner surface of the plate.Lips o are formed upon or fixed to plate f, so that when the strip h isplaced between platese and f these lips 0 may be bent over and pressedfirmly on or clinched against the back of plate 6, for securingall theparts of the binder firmly together. The lips 0 may be formed on plate6, to be bent over upon the inner face of plate f, or these lips may beformed on both plates; but the construction shown is preferred, as itleaves the inner face of the back part of the binder smooth for a betterfinish, and free introduction of the book or package within the binder.The binder is finally secured to the covers by gluing, riveting, orotherwise fastening the flaps L thereto, as indicated in Fig. 2.

To secure the book Z by the binder and within the protecting covers a,the plate 9 is swung over, as in Fig. 1, and the back of the book isthen passed into the pocket is, whereupon the plate g is swung over uponflange f bringing the gripping-jaw g to the vertical position, orthereabout, and bringing the back of the book firmly between jaw g andridge or bead m. It will be noticed that jaw g binds upon the book atone side of a line drawn through the center of head m, for more securefastening, all as shown in Fig. 2.

My improved detachable self binder and cover may be made to hold andprotect books or packages of any size or thickness desired, the holdbeing firin and the protection complete, and one book may be substitutedfor another both easily and quickly.

Having thus described my invention, I claim as new and desire to secureby Letters Patent 1. A detachable book cover constructed with covers a,and a binder consisting of plate 0, having lips j, in which the movableclampplate gis pivoted, a plate, f, clamped to plate 0 by lips 0, and afastening-strip, h, secured between plates cf, and having the flaps i,by

which the binder is held to the covers, substantially as shown anddescribed.

2. In a book-cover, the binder-plate c, having lips j, the platef,having lips 0, bent over on the back of plate 0, a flange, f, and a beador projection, m, the movable clamp-plate having gripping jaw g, andpivoted eccentrically with relation to jaw g in lips j of plate 0, andthe fastening-strip h, having flaps i, and secured between the plates 0f of the holder, all constructed and combined 'for operationsubstantially as shown and described.

3. A detachable book cover constructed substantially as sh own anddescribed, and consisting of covers a, base-plate 0, plate f, bout tofornia bead, m, and a pocket, is, clamping- 40 plate 9, hungecccntrically in cars of base plate 0, and a fastening-strip, h, clampedbetween the plates c and f.
